The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to undertake investigation of an engineering task to determine the mechanical fundamentals required by the task and integrating them into a task plan and report the plan and any investigations undertaken.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently:

• determine task parameters and context and identify and investigate required mechanical fundamentals
• evaluate task requirements, principles, techniques, typical applications and software
• plan the task
• integrate mechanical fundamentals to achieve task objectives
• communicate, cooperate and negotiate with stakeholders to achieve integration task
• report and document results.

Context of and specific resources for assessment 

• This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
• Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
• Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
• Assessment must cover the integration of two or more mechanical fundamentals to achieve the engineering task.
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
• Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
• Assessment may be applied under project related conditions (real or simulated) and require evidence of process.
• Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
• Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Mechanical and related fundamentals 

Mechanical and related fundamentals include fundamentals of:

• materials properties
• mechanics
• chemistry
• thermodynamics
• fluid mechanics
• fluid power
• electrical fundamentals

and may also include depending on the application:

• light, sound and electromagnetic effects

Machines, mechanisms and mechanical systems 

Machines, mechanisms and mechanical systems may include:

• piston and rotary displacement engines
• liquid, gas and steam turbines
• pumps and pumping systems
• compressors and pneumatic distribution systems

Systems thinking 

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain

Continuous improvement implementation  

Continuous improvement implementation may relate to plant, products, processes, systems or services, including design, development, implementation or manufacture, commissioning, operation or delivery and maintenance.

Improvement processes may include techniques, such as:

• balanced scorecard
• current and future state mapping
• measuring performance against benchmarks
• process improvement, problem solving and decision making
• data management, generation, recording, analysing, storing and use of software
• training for improvement systems participation
• technical training

Constraints and contingencies 

Constraints and contingencies may include:

• financial
• organisation procedural or culture
• physical constraints, such as limits to resources, limits to site access or logistical limitations

Sustainability 

Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:

• meeting all regulatory requirements
• conforming to all industry covenants, protocols and best practice guides
• minimising ecological and environmental footprint of process, plant and product
• maximising economic benefit of process plant and product to the organisation and the community
• minimising the negative WHS impact on employees, community and customer
